Light sequence out of sync

Reported via desktop in the Traffic lights (NH) category anonymously at 22:04, Thursday 11 January 2024

Sent to National Highways less than a minute later. FixMyStreet ref: 5431833.

The traffic lights for the A11 northbound, A47 westbound slip road and also the traffic lights on the Thickthorn roundabout preceeding the A11 northbound are all out of sync. Where normally traffic would have continuous flow there is an issue of green light traffic having nowhere to go as the ahead traffic is stuck on red lights from a previous junction. This is casing delays when exiting the A47 westbound onto the roundabout, and also traffic from the Norwich Road onto the roundabout. The peak times will always have traffic but there is excessive amounts due to incorrect light sequences. This issue has been in place for months but as of recent has changed again for the worse.
